Description
Technical Field
[0001] The utility model relates to the technical field of pipeline installation, in particular to a highly reliable and anti-loosening fixing structure for vehicle frame pipelines. Background Technique
[0002] When installing pipelines near the vehicle frame, the pipelines are mainly fixed in the following two ways: one is to use a clamp, which is usually composed of two semi-cylinders and a bolt standard part connecting the semi-cylinders. By opening holes in the vehicle frame, the pipelines arranged along the frame are fixed by the clamp. This fixing method requires a large number of clamps and bolts, increasing the weight and affecting the assembly efficiency. At the same time, during the long-term operation of the vehicle, there is a possibility that due to the loosening of the bolted structure, the bolt standard parts are lost and the clamp is loosened, resulting in the failure of pipeline fixing.
[0003] The second is to use various types of cable ties, including rivet cable ties, to bundle the pipelines arranged along the vehicle frame by using pre-opened holes in the vehicle frame. Since the performance of the cable tie is closely related to climate factors such as environmental temperature and humidity, the cable tie will inevitably age over time. Therefore, in the later stage of vehicle use, there is a risk of pipeline fixing failure due to the aging and breakage of the cable tie. Summary of the Invention
[0004] In order to solve the problem that common pipeline fixing measures have a risk of fixing failure, the utility model provides a highly reliable and anti-loosening fixing structure for vehicle frame pipelines, which comprehensively utilizes a rubber-coated clamp, a fir tree reverse tooth, a standard thread and a slot structure to achieve long-term reliable fixing of the pipelines arranged along the vehicle frame.
[0005] To achieve the above object, the technical solution adopted by the utility model is:
[0006] A highly reliable and anti-loosening fixing structure for vehicle frame pipelines, used for fixing pipelines arranged along the vehicle frame, includes a rubber-coated clamp body, a fir tree thread pin and a flange nut. The rubber-coated clamp body is a bendable "C"-shaped structure, which is convenient for adjusting the opening size of the rubber-coated clamp body. Clamping plates are symmetrically arranged on the upper and lower sides of the opening of the rubber-coated clamp body, and the positions of the clamping plates change when the opening size is adjusted;
[0007] After the clamping plates on both sides are attached up and down, they pass through the vehicle frame and are connected to the fir tree thread pin. The fir tree thread pin is a cylindrical structure, which includes a standard thread section and a fir tree reverse tooth section integrally formed up and down. A slot is opened on the fir tree thread pin, and the two attached clamping plates are clamped into the slot to prevent the rubber-coated clamp body and the fir tree thread pin from separating from each other;
[0008] After the flange nut passes through the fir-tree shaped reverse tooth section, it is connected to the standard thread section, ensuring the reliable installation of the rubber-coated clamp body and the fir-tree thread pin.
[0009] Furthermore, the rubber-coated clamp body is a "C"-shaped structure made of DC01 sheet material, which is flexible and easy to bend. A protective sleeve is sleeved on the rubber-coated clamp body. The protective sleeve is a flat ring made of silicone, preventing wear between the rubber-coated clamp body and the pipeline.
[0010] Furthermore, the clamping plate is comb-shaped and integrally formed with the rubber-coated clamp body. The width of the clamping plate is smaller than that of the rubber-coated clamp body, facilitating matching with the fir-tree thread pin. The length direction of the clamping plate is consistent with the radial direction of the rubber-coated clamp body.
[0011] Furthermore, the clamping groove is comb-shaped and has the same length as the clamping plate. The clamping groove extends into the fir-tree shaped reverse tooth section after passing through the standard thread section along the axial direction of the fir-tree thread pin, increasing the contact area between the clamping plate and the fir-tree thread pin. One side of the clamping groove radially penetrates the fir-tree thread pin, and the other side is a closed structure, facilitating the insertion of the clamping plate into the clamping groove. The thickness of the clamping groove is the same as that of the two clamping plates. After the clamping plate is completely inserted into the clamping groove, it shall not protrude from the circumferential side wall of the fir-tree thread pin, ensuring that the flange nut can be smoothly pushed along the axis of the fir-tree thread pin and cooperate with the standard thread section.
[0012] Furthermore, the fir-tree thread pin is a cylinder made of PA46 material with stable performance. The length of the standard thread section is smaller than that of the fir-tree shaped reverse tooth section, and the outer diameter of the standard thread section is the same as that of the fir-tree shaped reverse tooth section. Standard threads are arranged on the outer surface of the standard thread section, and several reverse teeth in the shape of a fir-tree are arranged on the outer surface of the fir-tree shaped reverse tooth section.
[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] The structure of the present utility model is reasonably designed, enabling efficient assembly of pipelines while eliminating the risk of pipeline fixing structure failure during long-term vehicle operation. The rubber-coated clamp body is made of DC01 material, facilitating the opening and closing of pipelines and enabling the loading and restraint of pipelines. A protective sleeve is arranged outside the rubber-coated clamp body, preventing the rubber-coated clamp body from wearing the pipeline.
[0015] The rubber-coated clamp body of the present utility model is formed by combining a colloid with the surface of the clamp body substrate through certain technological means to form a rubber coating, which plays a role in protecting the substrate. The rubber-coated clamp body is provided with two integrally formed clamping plates. The rubber-coated clamp body is clamped with a fir-threaded clamping pin through the clamping plates, which can prevent the fir-threaded clamping pin from detaching from the rubber-coated clamp body and also avoid the rotation of the fir-threaded clamping pin relative to the rubber-coated clamp body. After the fir-threaded clamping pin is clamped with the rubber-coated clamp body, a flange nut is installed on the fir-threaded clamping pin, ensuring the reliability of the clamping. At the same time, the fir-shaped reverse tooth section on the fir-threaded clamping pin prevents the flange nut from loosening and retreating.
[0016] The present utility model can reduce the usage amount of standard parts when using conventional clamps to fix pipeline systems, and at the same time solve the problems of clamp loosening caused by the loss of standard parts and the failure of the pipeline fixing structure. It also solves the problem of the failure of pipeline fixing caused by the aging and fracture of various types of cable ties, including rivet cable ties, during the later stage of vehicle use.

[0027] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings:
[0028] As Figures 1 to 9 shown, a highly reliable and anti-loosening pipeline fixing structure for automobile girders is used for fixing the pipeline 8 arranged along the automobile girder 7. The fixing structure includes a rubber-coated clamp body 1, a fir-threaded pin 2 and a flange nut 3. Through the combination of the above components, the pipeline 8 can be detachably arranged on the automobile girder 7, so as to fix and arrange the pipeline 8 along the automobile girder 7, as Figure 1 and Figure 2 shown.
[0029] The rubber-coated clamp body 1 is a bendable "C"-shaped structure body. In order to enable the rubber-coated clamp body 1 to be bent, a special material is used for manufacturing. Specifically, the rubber-coated clamp body 1 is a "C"-shaped structure body made of DC01 sheet. As a cold-rolled steel sheet, DC01 sheet has the characteristics of being soft and easy to bend. The base material thickness of the rubber-coated clamp body is 1.0 mm. At the same time, a colored zinc plating layer is provided on the surface of the base material of the rubber-coated clamp body 1. The colored zinc plating layer is a layer structure formed through the colored zinc plating process, so that the rubber-coated clamp body 1 has anti-corrosion performance.
[0030] On the basis that the rubber-coated clamp body 1 can be bent, the opening size of the rubber-coated clamp body 1 is adjustable. Therefore, the rubber-coated clamp body 1 can be a "C" shape structure. When the opening is closed, the rubber-coated clamp body 1 can also be a circular structure. After the opening of the rubber-coated clamp body 1 is opened, it is convenient to put the pipeline 8 into it. After the opening is closed, it can restrict the pipeline 8 and fasten multiple pipelines 8 together, playing a role of restraint and bundling to prevent the pipeline 8 from slipping out of the rubber-coated clamp body 1, as Figure 3 and Figure 4 shown.
[0031] To prevent the rubber-coated clamp body 1 from directly contacting the pipeline 8, a protective sleeve 4 is provided over the rubber-coated clamp body 1. The protective sleeve 4 is a flat ring made of silicone. The protective sleeve 4 is of a certain length and can be completely fitted over the rubber-coated clamp body 1, thereby forming a silicone protective layer on the outside of the rubber-coated clamp body 1, effectively preventing abrasion of the pipeline 8.
[0032] Clamps 5 are symmetrically positioned above and below the opening of the rubber-coated clamp body 1. Clamps 5 are integrally formed with the clamp body 1. The clamps 5 are narrower than the clamp body 1 to ensure compatibility with the fir-threaded bayonet pin 2. Their length aligns radially with the clamp body 1. When the clamp body 1 is opened, the two clamps 5 move away from each other. When the opening is closed, the two clamps 5 can be stacked and fitted together.
[0033] The fir threaded pin 2 is a cylindrical structure. Specifically, the fir threaded pin 2 is a cylinder made of PA46 material. Therefore, the fir threaded pin 2 can be used in an ambient temperature range of -40°C to +130°C. The performance of the fir threaded pin 2 is more stable and reliable.
[0034] The fir-tree threaded bayonet 2 comprises a standard threaded section 21 and a fir-tree-shaped inverted tooth section 22, each integrally formed at the top and bottom. The standard threaded section 21 is provided with standard threads, while the fir-tree-shaped inverted tooth section 22 is provided with several inverted teeth shaped like a fir tree. The standard threaded section 21 is shorter than the fir-tree-shaped inverted tooth section 22, and their outer diameters are identical, ensuring that the flange nut 3 can pass smoothly through the fir-tree-shaped inverted tooth section 22.
[0035] The rubber-coated clamp body 1 needs to be connected to the fir-tree threaded bayonet pin 2. After the connection, the two are arranged on both sides of the automobile beam 7. At the same time, under the action of the flange nut 3, the three components are fixed to the automobile beam 7. Specifically, the clamping plates 5 on both sides are fitted up and down, and then pass through the automobile beam 7 to connect to the fir-tree threaded bayonet pin 2. The connection here adopts a snap-on method, that is, the clamping plates 5 and the fir-tree threaded bayonet pin 2 are snap-fitted and installed.
[0036] In this embodiment, the clamping plate 5 is in the shape of comb teeth, and a clamping slot 6 is provided on the fir-tree thread clamping pin 2, and the clamping slot 6 is also in the shape of comb teeth. Figure 5 and Figure 6 As shown. The slot 6 axially passes through the standard thread section 21 along the fir-tree threaded bayonet 2 and then extends into the fir-tree-shaped inverted tooth section 22. The slot 6 and the bayonet plate 5 have the same length, with the length of the slot 6 being A. One side of the slot 6 radially passes through the fir-tree threaded bayonet 2, with the width of the slot 6 being B. The thickness of the slot 6 is the same as that of the two bayonet plates 5, with the thickness of the slot 6 being C.
[0037] Two mutually fitting clamping plates 5 are clamped into the clamping groove 6, and the clamping plates 5 can be hidden in the clamping groove 6 without protruding from the fir-threaded pin 2. In this way, the fir-threaded pin 2 cannot be separated from the rubber-coated clamp body 1, nor can it rotate relative to the rubber-coated clamp body 1. The flange nut 3 passes through the fir-shaped inverted tooth section 22 and is connected to the standard thread section 21 to press the clamping plate 5, and also fixes the rubber-coated clamp body 1 and the fir-threaded pin 2 together on the vehicle frame 7. The fir-shaped inverted tooth section 22 plays a role in preventing the flange nut 3 from loosening.
[0038] When the utility model is installed, first pull open the rubber-coated clamp body 1, place the pipeline 8 into its inner circular ring structure, then fold the rubber-coated clamp body 1 until the clamping plates 5 on both sides are completely fitted and aligned, and the rubber-coated clamp body 1 closes the opening, as Figure 7 shown. Then pass the clamping plate 5 through the hole pre-opened on the vehicle frame 7, take the fir-threaded pin 2 and move it along the axis of the rubber-coated clamp body 1 to install the fir-threaded pin 2 until the clamping groove 6 in the fir-threaded pin 2 is completely fitted with the clamping plate 5 on the rubber-coated clamp body 1, as Figure 8 shown. After the installation is in place, take the flange nut 3 with its flange side facing the vehicle frame 7 and push it along the axis of the fir-threaded pin 2 until the flange nut 3 contacts the standard thread section 21. At this time, use a tool to tighten it until the flange surface of the flange nut 3 is tightly attached to the vehicle frame 7, as Figure 9 shown.
[0039] After the vehicle has run for a period of time, even if the flange nut 3 loosens slightly and moves backward, since the major diameter of the thread of the flange nut 3, that is, the nominal diameter, is the same as the outer diameter of the fir-shaped inverted tooth section 22 of the fir-threaded pin 2, the thread teeth of the flange nut 3 will be blocked by the fir-shaped inverted teeth of the fir-threaded pin 2, thus preventing the flange nut 3 from falling off. At the same time, since the fir-threaded pin 2 and the rubber-coated clamp body 1 are matched through the clamping groove 6 and clamping plate 5 structure, it is ensured that the rubber-coated clamp body 1 cannot be disengaged from the opening of the vehicle frame 7, and finally the long-term reliability of the fixed structure of the pipeline 8 is guaranteed.
[0040] It should be noted that: the length of the standard thread section 21 of the fir-threaded pin 2 is equal to or slightly greater than the thickness of the hexagonal flange nut 3, ensuring that there is enough fitting length between the hexagonal flange nut 3 and the standard thread section 21 of the fir-threaded pin 2. At the same time, it is avoided that due to the too long length of the standard thread section 21, the hexagonal flange nut 3 has too large a loosening amount.
[0041] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent should be included in the scope of the patent application of the present utility model.
